夢幻の風花　シラユキPhantasmagoric Snowy Wind Shirayuki

Ability:
自【Ｖ】 : LIMIT BREAK 4(This ability activates when you have four or more damage): [Counter Blast *1, discard a "Phantasmagoric Snowy Wind Shirayuki" from your hand] at the beginning of the guard step when this unit is attacked, you may pay the cost. If you do, select an opponent's attacking unit, the selected unit losses 20000 power until end of that battle.
永【Ｖ／Ｒ】 : 盟主(if you have a unit of a different clan from this unit, this unit may not attack)

Seems like all the RR units' ability has been released.
